The term "bargain" is used generously in real estate. But when it comes to buying a house, how do you know if you're truly getting a deal?

Online real estate listing site Trulia decided to find out if homes listed on its site and claiming to be a "bargain" - or something similar - are really discounted (or listed for less than the median listing price). Its analysts considered homes in the 100 largest housing markets across the US.

Trulia discovered that only 55 of the country's largest housing markets actually offer homes at a discounted price. 10-20% of them are located in the Bargain Belt, the name given to the highly affordable markets in the South and Midwest, and they often have discounts of more than 10% off the median listing price.

In contrast, the Costly Coast, or expensive metro areas in the West and Northeast, have the smallest discounts on homes, often ranging from 2-4%.

Two housing markets in Ohio - Toledo and Dayton - came out on top as the most discounted housing markets in the country.
